I checked your website, and I can give you a fresh new look for it. I'm native from Argentina, so I will have no problems with the language.
I was thinking about designing a Joomla site for you, so you can update it periodically without any expertise. Will also give you a fresh look, respecting the original colors and image tendencies.
We can communicate periodically through Skype, MSN Messenger, GTalk, Whatsapp and e-mail.
I will deliver your site in about 7 to 10 days.
